BASIC (Beginner's All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages whose design philosophy emphasizes ease of use. This app uses the free/open source (GPL) FreeBASIC compiler (https://www.freebasic.net) as backend. FreeBASIC is a high-level programming language supporting procedural, object-orientated and meta-programming paradigms, with a syntax compatible to Microsoft QuickBASIC.

Limitations:
- Internet connection is required for compilation
- Only one file can be run at a time
- Maximum program running time is 20s
- Some file system, network and graphics functions may be limited
- This is a batch compiler; interactive programs are not supported. If your program provides an input prompt, enter the input in the Input tab prior to compilation. See the Reference tab in the app for code examples
